Frankfurt, February 2025 – EuroWindoor provided feedback on the EU Platform on Sustainable Finance’s draft report regarding the review of the Taxonomy Climate Delegated Act and additional technical screening criteria. It is important to EuroWindoor to support the ongoing revision process to ensure that criteria for windows and curtain walling are aligned not only with the sustainability goals but also with real-world conditions.
EuroWindoor commented that the feedback submitted lastly in 2023 via the stakeholder request mechanism does not appear to have been considered in the draft report. EuroWindoor urges the Platform to take previous stakeholder input into account to ensure an effective and practicable framework.
The following key concerns remain unresolved and have been raised again:
- U-value thresholds: The current approach of predetermined U-values does not accurately reflect energy efficiency potential. An energy balance approach, which considers both heat losses (U-value) and solar gains (g-value) in relation to climate conditions, is the only reliable method to assess energy efficiency of transparent building elements.
- Curtain walling allocation: Curtain walling shares more characteristics with windows than opaque walls and should be categorized accordingly. Adjusting the allocation to windows would provide more appropriate screening criteria.
- Regional differentiation: Threshold values should reflect geographical and climatic variations rather than applying uniform EU-wide criteria. This will ensure better resource and energy efficiency.
Furthermore, the Platform’s report acknowledges that time constraints and limited resources have hindered the thorough assessment of stakeholder input, with a focus placed on additional characteristics instead. EuroWindoor emphasizes that existing shortcomings must be addressed first to prevent compounding issues during implementation. The usability of the Taxonomy must be enhanced by resolving current challenges before expanding its scope.
